WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 663,363.dated December4, 1900.

Original application led April 8, 1899, Serial No. 712,252. Divided andthis application filed September 12,1900. Serial No.

To all whom it may concern.'

Beit known that LTHOMAS I. RANKIN,a citizen of the United States,residing in Philadelphia,Pennsylvania,have invented certainImproveinents in Vater-I-Ieaters, (beinga division of au application forpatent filed by me on April 8, 1899, under Serial No. 712,252,) of whichthe following is a specification.

The object of my invention is to construct a gas-heater for heatingwater which can be used in place of the ordinary water-back of a rangeor can be used in addition to said waterback, as desired.

rlhis application is a division of an application filed by me on the Sthday of April, 1899,

Serial No. 712,252.

In the accompanying drawings, Figure 1 is a longitudinal sectional Viewof my improved water-heater on the line 1 1, Fig. 2; and Fig. 2 is atransverse sectional view on the line 2 2, Fig. 1.

A is a water-chamber made of cast metal and preferably in a singlepiece. In the present instance it is quadrangular in form, having sidebars a a and cross-bars ct at top and bottom and intermediate cross-barsd2. All the bars are tubular and are so shaped and arranged as toprovide for the ready circulation of the water to be heated. By makingthe bars tapered in cross-section accurate castings can be readilyproduced. The crossbars a2 are staggered, as shown, and the end bars dare corrugated to correspond therewith. 'Ihis arrangement deflects theproducts of combustion, so that all portions of the casting will besubjected to the direct action of the same.

The water-chamber Ais inclosed within a casing B. This casing in thepresent instance consists of a lower frame B, a cap-plate b, sides b,and end plates b2. The cap-plate b is flanged and the side plates aresecured to the said Flange and to the bottom plates by screwbolts orrivets. In the present instance the side and end plates are made of asingle sheet of ornamented metal lined with a non-couducting material,so that heat will be retained in the water-heater.

(No model.)

The cap-plate b has a fine-opening c, above which is ashort stack C tocarry off the waste 5o products of combustion.

Forming part of the lower frame B' is the cap d of the burner D. Arms dconnect the cap with the portion of the frame secured to the casing.Secured to the capd isa troughshaped bottom section D', the edges ofthis section fitting snugly against the iianges of the cap, as shown inFig. 2, and screw-bolts cl2 pass through the cap and trough-section,holding the parts together.

The cap d has a series of perfor-ations z for the escape of gas.Agas-pipe I is connected to one end of the burner, as shown in Fig. 1.The pipe is provided with the usual valve (not shown) and an air-valvei. Air and gas are mixed at the valve il, and the mixture enters theburner, escaping through the perforations and mixing with a certainquantity of air entering through the space between the ange of the frameB and the depending 7o cap b.

At each upper corner ot the water-chamber A are threaded bosses e e, andin the lower cross-bar al are threaded bosses e' e'. The water-pipes EE, leading to the boiler, are coupled to one of the upper bosses and'toone of the lower bosses. The openings in the other two bosses are closedby suitable plugs.

By providing the bosses as shown the waterheater can be used eitherright or lett handed. 8o

My improved water-heater can be attached to the circulating-pipes of anordinary range using a boiler and water-back or may be usedindependently of the water-back, if desired.

As soon as the water in the boiler or other receptacle reaches a certaintemperature the gas can be turned off, thus economizing in the fuel. Thewater-heater may be coupled to a supply-pipe at any point desired and 9oWater heated independently of a range or a water-heater at the range.

I claim as my invention- 1. A casting having tubular corrugated sidebars and tubular cross-bars communieating with the tubular side bars,said crossbars being staggered, in combination With a casing inclosingsaid casting and a burner under the said casing, substantially asdescribed.

2. The combination of acasting made in a single piece and having tubularcorrugated side bars and tubular cross-bars communicating with thetubular side bars, the said cross-bars being staggered and tapered, witha casing inclosing the said Watercl1amber, and a burner under the saidcasing, substantially as described.

3. The combination ot' a'Water-chamber, a casing inclosing saidWater-chamber, said casing consisting of an open base-frame, a top platehaving a flue -opening therein and flanged, with a side plate or platessecured to the base-frame and the flanges of the top plate, alongitudinally-arranged burner directly under the casing, the cap of theburner forming part of the base-frame of the casing, the trough-shapedlower portion of the burner being secured to the cap, and a gas pipecoupled to the said-burner, substantially as described.

4. The combination of a water-chamber, a casing in which theWater-chamber is mounted, said casing having a base-frame, a burnersituated under the casing, the cap of lsaid` name to this specificationin the presence of two subscribing witnesses.
